Methodology of avoiding condensation and downdraft in displacement ventilation plus cooling ceiling system
置换通风加冷却顶板系统避免结露和下降气流的方法
Currently, displacement ventilation and cooling ceiling system (DV/CC) has two main disadvantages: first, condensation will happen when the radiant panel temperature is lower than the dew point temperature of air around it;second, the downdraft from the cooling ceiling destroys the airstream shape of DV, which reduces indoor air quality.
目前冷却顶板/置换通风系统有两个突出问题:冷却顶板易“结露”;冷却顶板形成的“下降气流”破坏了置换通风的流型,降低了空气品质。
